WATER-HEATER.

SPECIFICATION forming part of Letters Patent No. 633,769, dated September 26, 1899. I

Application filed November 18, 1318. Serial No. 696,782. (No model.)

Be itknown that I, MICHEL SCHAAOK, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in \Vater Heaters; and I do here bydecl are the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.-

My invention relates to a novel construction in a water-heater, the object being to provide a simple, cheap, and efficient device of this character; and it consists in the features of construction and combinations of parts hereinafter fully described and claimed.

In the accompanying drawings, illustrating my invention, Figure l is a top plan view of a water-heater constructed in accordance with my inventionf Fig. 2 is a central vertical section of the same on the line 2 2 of Fig. 1. Fig. 3 is a horizontal section on the line 3 3 of Fig. Fig. 4 is a similar section on' the line 4 4 of Fig. 1.

Referring now to said drawings, A indicates a cylindrical casing consisting of a plurality of interfittin'g sections a, mounted one upon the other. Each of said sections aexcept the lowest is provided with a conically downwardly-inclined bottom plate 1, provided with a central opening 2, below and around which. an inversed cone 3, of wire-cloth, is secured. A solid plate 4 of similar shape to the plate 1, but inversely inclined, is mounted below each of said plates 1 and carries a wirecloth cylinder 5, adapted to rest upon the next lower plate and be supported thereby, being held concentric with the casing A by the springs 6, secured to the walls of'said sections and curved at their lower ends, which bear against the edges of said plates 4. Said plates 4 are of smaller diameter than said sections'a, so as to leave annular passages 7 between said plates and the wall of said casing.

Each of said bottom plates 1 and said solid plates 4 are provided with corrugations 8, extending practically tangentially from said openings 2 in said plates 1 to the outer edges of said plates and in the case of the plates 2 from a corresponding central plane portion 9 to the outer edges of the sheets. I

Mounted upon the plate 1 of the uppermost section a is a ring 10 concentric with and adjacent the outer wall, so as to form an annular passage 11 between said ring 10 and said wall of said section. A feed-pipe 12 enters said annular space 11 and feeds the water thereto. Below the delivery end of said pipe is an inversed-V-shaped plate 13, which serves to cause the water to flow equally around said annular passage in opposite directions, thus serving to distribute it more equally over the plate 1. The water flows from said annular passage 11 through interstices formed by the depressed corrugations of said plate and follows said corrugations to the center, whence it flows upon the wirescreen cones 3, which serve to guide it to the center of the plate 4 next below said upper plate 1. Thence it flows toward and over the outer edges of the plate 4 upon the next plate 1, and so on, until it flows over the edge of the lowest plate 4, and thence into an an nular passage 14, formed adjacent the outer wall of the lowest section a by the annular plate 15, which is V-shaped in cross-section and inverted, thus leaving a central opening 16 in the bottom of the lowermost sect-ion. An outlet-pipe 17 leads from said annular passage 14. Said casing A is supported upon legs 18 over a gas-stoveor other heater, the

tion always opposite to the flow of water. By bringing the hot gases in direct contact with the water I find that all the heat is absorbed thereby and the water heated to a very high degree duringits passage from the inlet to the outlet end of the device.

I claim as my invention- 1. A water-heater comprising a plurality of interfitting cylindrical sections mounted one upon the other, transverse corrugated plates interposed in said sections inclined downwardly toward the center and provided with a central opening, transverse corrugated plates of lessdiameter than said sections and inclined downwardly from the center toward the edges, wire cloth cylinders secured to said last-named plates and adapted to guide the waterupon the next lower plate, substantially as described.

2. A water-heater comprising a casing provided with an annular receptacle at its lower end, and with a central opening, a perforated heat from which passes upwardly in a direc- ICO cylinder of less dia-metcrand concentric with said casing standing in said annular receptacle, a plate inclined downwardly from its middle portion to its periphery mounted upon said perforated cylinder and having approximately the same diameter, a plate inclined from its periphery downwardly toward its center and having a central opening,rnounted above said first-named plate, and devices for feeding water upon said last-named plate, substantially as described.

3. A water-heater comprising a casing provided with an annular receptacle at its lower end, and with a central opening, a perforated cylinder of less diameter and concentric with said casing standing in said annular receptacle, a plate inclined downwardly from its middle portion to its periphery mounted upon said perforated avlindm' and havinu ann vL mately the same diameter, a plate inclined 2 from its 'periphery downwardly toward its center and having a central opening,mounted above said first-named plate, an inverted perforated cone secured around said opening in said last-named plate, a second perforated.

cylinder carrying a plate similar to said firstnamed plate, the cylinder being mounted I upon said plate having a central opening,

' means for centering said perforated cylinders
